OK, that's good info.  You can take a laptop, shock mount it inside a
briefcase, and go that way;  Hard to extend it, yes.

A PC/104 or "Biscuit PC" form motherboard, or something like the
Timeline or EIO 486's could be used, displays are a problem (and LCD
displays are NOT too rugged!  Cost $50ish+ to replace, if you go LCD you
might buy 2 of them...)  No PCI slots there.  The EIO machine could be
taken apart giving you 2-3 ISA slots free, am talking with one guy about
that for his situation.  The Timeline machine has 1 ISA slot free.

Lessee, PCI *and* ISA?  OK, how about this;  Let's discuss the monitor
separately for right now.  Take a Momboard, mount it on a 1/4" plywood
slab or 1/8" metal sheet on standoffs with your HDD and floppy
alongside, put a power supply in the box (Could go with a DC-DC
converter without a fan, maybe?  See the MP3 player info on the Web.)
Rig it so you have to open the briefcase to use it, probably, and use a
waterproof case.  Use shock mounts to attack the metal sheet to the
briefcase.

Display;  You could use a Liquid Image M1 (320x240 pixel grayscale)
monocle, $500, and store it in the case when not using it;  Could use a
Pen Tablet type computer, view it through a Plexiglass plate.

Keyboard:  Keyboard "Rubber"?  Plastic "ziplock" bag over the board?  IR
remote keyboard?  Twiddler inside a plastic bag?  Hmmm...

Also, what sort of CPU power do you need?  Would a 486 sx33 or something
work for you?  (There are LOTS of possibilities here, from a PC110 with
port replicator to your choice of keyboard/display, to those pen tablet
machines like the IBM ThinkPad 730T, or Dauphin DTR-1, to ???)  Sounds
sorta fun to me <G>  We can go off-list if needed.
